ispconfig 3 login problem

just installed fedora 10 with ispconfig 3, worked perfect the first time i logged inwww.myserver.com:8080/ i changed the password, looked around, then logged out, now i can't login with either the admin admin, or the user/password i added

Please never change the mysql password of the ispconfig user manually. The old password is stored in the ispconfig config.inc.php files, take this password and use it to set the password in mysql back to the old value.
